The probabilistic lava flow map produced by Q-LavHA should be interpreted with care. Q-LavHA is a plugin which attempts to approach the reality of a channelized ʻaʻā lava flow inundation as accurately as possible. However, the outcome of the simulation depends on the quality of the DEM used and the selected simulation parameters. The probability of being inundated has to be interpreted as having a higher or a lower chance to be inundated. We consequently recommend the users to interpret the results as the sum of the trajectories a flow can potentially follow if an eruption occurs. More detail and recommendations can be found in Mossoux et al. (2016).


Q-LavHA has been designed to run in QGIS. Therefore, it is compulsory to install QGIS (minimum version 2.14) before installing Q-LavHA. All the information you need to install the plugin in QGIS is describe in the user manual
